Hi,
I've ported IB's Tws API to Rust. This is a port of the TCP api not a rust wrapper/client to their REST api (I think there are a few crates that do that). I plan to eventually submit it to crates.io, but would really like to have others who have more Rust experience to give it a review first. Also, my testing has been manual and I intend to write some automated tests.
Please have a look and let me know if you'd like to review it, and if you find a bug or something, feel free to submit a pull request.
Thanks!
